To (all, whom it may concern Be it known that we, HORACE B. GALE, of

Natick, in the county of Middlesex, and FRED M. DEWING, of Boston, in the county of Suffolk, State of Massachusetts, citizens of the United States ,have invented anew and useful Improvement in Means for Producim Sound- Vibrations in Water, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings,

- forming a part of this specification, 1n explaining its nature.

The invention relates to a means for pro ducing sound-vibrations in water, whereby, the sound-vibrations may be imparted to the water and be carried thereby as a transmittory medium, and which means, moreover, is

so adapted as to be actuated or influenced.

by the movement of the water or by hand or other mechanical expedient.

The object of our invention is to produce a submarine sound signaling apparatus which shall have effective sound-producing cgen ed in the water or otherwise manipu ated,

and which is so constructed as to be easilyacted upon or operated by the motion of the boat or other floating structure from which the apparatus is sus ended.

The invention is i lustrated by the acoom panying drawings, forming a part of this specification, wherein- Figures 1 and 2 show in elevation contrast ingviews of the sound-producing apparatus Fig. 6 shows a detail of construct on to which i as suspended from a boat. Fig. 3 is a cross vertical section with a portion of the soundproducing apparatus shown inside elevation. ig. 4 shows the same, but with a change in the disposition of the operative parts to which reference will hereinafterv be made. Fig. 5 shows, essentially, an end elevation of a portion of the sound-producing apparatus.

" reference will hereinafterbe made.

"prising two cords.or'equivalentrneans C C, p the cord C being fixed to the top of said shell Referring to the drawings, A indicates the outer shell. or case oi the sound-producing device, in which is contained the sound-producing mechanism. The outer shell or case is shown suspended from a floating structure, as a boat B, the means of suspension comor'ca'se, either with a direct or through some auxiliary connection, and the cord C assistmg m the suspension of the shell or case and connecting with the mechanism on the insidethereof, as will hereinafter be explained. The cords at their upper ends are secured to the side of the boat, ranged fore and aft at the points 1 and 2, respectivel (see Fig. 1,) or

upon opposite sides thereo at the respective oints 3 and 4, as may be seen in Fig. 2, this in order that the pitching or rocking motion ofthe boat imparted to it by the natural movement of the water or otherwise obtained may be most effectively utilized.

The exterior shell or case A is made pref.- erably of metal and of approximately a cylindrical formation. Upon the inside there-.

of, projecting inwardly, is an annular ring or bow D, whichmay be of an integral or auxiliary formation with that of the case. In the drawings it is shown formed integrally with the case. By forming the shell or casewith the ring thus disposed it souuds,whenstruck, with a relatively high -pi tcli,which-has been found to be most efiective in submarine Signaling. Moreover, formed as it is the shell or case can be made relatively light in structure, which especially fits it for suspension in .the, water from a small boat or to be otherwise manipulated. On the inside the shell or case gives a large chamber for the striking mechanism, while on its outside surface it presents a smooth rounding exterior surface, on which seaweed or other debris cannot easily lodge. E represents a striker adapted to strike the ring D, so causing it to sound. The striker E, as shown, is pivoted on the pin 1), which passes throu h a slot sin the striker-arm and is held by a ame M, attachedto the case A, which frame may, if desired, be formed integrally therewith. In this connection it is to be noted that the slot 8,. by which the striker-arm is pivotally secured to pin p, has a somewhat elliptical formation, whereby the striker-arm has a slight degree ofplay upon said pin, this for purposes as will hereinafter be explained. "It is also to be noted that the frame M is extended up with a neck, as it were,.through an opening formed in the top of the case, the case practically. resting upon shoulders formed thereby, and through which extended neck asses the pin a, to which the end of the cor C is secured by suitable link connection. This is an arbitrary feature of construction, however, for the case itself may just as well be extended to receive the direct connection of the cord C. Secured to. the upper ing laterally from either side thereof are the pins p 19 respectively. Attachedt'o these separate pins are the ends of respective springs F F. The springs at their opposite TO ends are secured by suitable pin connections p to the arm 9 of the rocker-lever G, which is pivotedat the point p to the frame M. Pivoted at the point is to the arm 9 of the said rocker-lever is a link H, carrying at its x 5 upper end one or more pulleys I, with a connecting-pin i, and around which pulleys-the cord 0 is passed to where its end is secured to the shell or ,case A at the oint c. The pulley or pulleys I are preferab y supplemented by the pulley cord C is also passed after I being passed around the pulley I before its end is fixed. The pulleys J, it 1s to be noted, are arranged in the top of the shell or case A orin the neck of the frame M, which extends through the top of said-case, and preferably by the same pivotal pin a bywhich the end of the cord 0 is secured thereto, as before explained. Carried by the arm g of the said rocker-lever G and by the same connecting-pin which secures the link 11 is the latch L. It is to be noted by reference to the detail of construction shown inFig. 6 that the saidarm of the lever is made cleft at its end to receive said latch and also to form'two stop-surfaces therefor, as it were, 9* g", by contacting with which the latch-has a certain dc'iined'radial swing, the surface g defining the swing of the latch in one direction by the contact of its 40 rear end against said surface (see Fig. 3) and the surface g, if the occasion demands, de-

fining the swing of the latch in the opposite direction, this by the contact of its side against said surface. The latch is overweighted, so as to assume a normal position like that shown in thofull lines on Fig. 3, with its rear end contacting with the stop-surface g thereof,and thelatch, moreover, is of such relative size that. it will contact with the cam-surface 'l of the striker-arm formed on the side thereof when the rocker-lever is turned or drawn up; but to this reference will hereinafter be made. The normal position of the elements thus combined is substantially like as shown in Fig. 3, withthe p0,- sition ofthe -.striker like as shown -in .the

dotted lines thereof, with the' striker-head slightly drawn away from contact. with the ring it). The elements are held to assume this normal position by reasonof the drawing-tension of the springs F F, at their one end each drawing upon the rocker-lever G and at their other ends drawing upon the upwardly-extending end of the striker-arm, and it is to be noted that the'striker-head is end of the striker-arm and project-- or pulleys J, around which the drawn away from a normal contact with the rin D by reason of the fact that the upper en of the striker-arm is drawn by the springs against a stop N, which is attached to the inner side ofthe case A, so that the striker-arm fulcruming against the stop is drawn backupon its.p1votal connection by reason of the extension of its slot .9 to where its head assumes the relative normal position aforesaid,

this being commensurate with the amount of 4 the slots extension.

The operation of the sound-producing apparatus. 1s as follows 'With the cords C C secured to the side of the boat 'foreand aft or to opposite sides'thereof .whatever pitching or rocking motion is imparted to the boat'by the motion of the water results in the cords C Cbeing alternately slackened and'tightened, so that the whole or part of the weight of the case A and inclosed parts will be transferred alternately from the cord C to the cord C, and vice versa. When the pendent weight of the a paratus comes upon the cord C, there wil f be no resultant influence exerted upon the parts constituting the striking mechanism by reason-of the fact that the cord C is fixed to the case orto the frame extending therefrom, as before referred to; but when ,the cord C becomes slackened and the weight of the apparatus is transferred to the cord C this becomes tightened, and consequently as it connects with the interior mechanism the resultant operation would beto draw u the pulleys I, carrying with them the link I and so turning the rocker-lever G. The turning or drawing up of the rocker-lever causes-the spri gs F F to be somewhat extended by the drawing stress of the lever-arm g,.and when the rocker-lever has been sufficiently-drawn up or turned the latch L, carried by its arm 9 and reinforced by its stop-surface 9 as before explained, is made to engage with the cam-surface T of the striker-arm, wherefore the striker-arm is thrown forw'ard, causing not only a further extension'of the springs, but also forcing the striker-arm into an operative positionI When the parts have assumed a position substantially like that shown in Flg. 4, a slight further motion of the rocker-arm G carries the latch L beyond the end ,of the cam-surface T, with which it engages, and the striker-arm becomes released. The retraction of the springs F F then throws the striker E down to its normal position, (shown in the dotted lines of Fig. 3,) and the momentum thus acquired by the striker carries it beyond this position to that shown in the full lines of Fig. 3, or to where its head contacts with the ring D, causing it to sound.

This further movement of the striker, caused i head of the striker has contact with the ring; but after such contact, the upper end of'the striker E then fulcruming agamst the stop N, the tension of the springs draws the striker back so far as the extension of theslot s will allow onto the that shown in t 1e dotted lines of Fig. 3. When the cord 0 is slackened by the weight of the apparatus being transferred to the cord- C and its drawing stress accordingly let go, then the further retraction of the-springs F F draws the rocker-lever back to its normal position, like that shown in Fig. 3. During the withdrawal of the rocker-lever the latch L is carried by it and takes. a position substantially like that. shown'in the dotted lines of Fig. 3 until it has passed the end of the cam-surface T. of the striker-arm, when it gravitates to the normal position, (shown in the full lines thereof,)- ready for engagement r with the saidcam-surfaceof the striker-arm,

when the parts are a am actuated. Any

. displacement of the late is dprevented by the back stop-surface g forme in the lever-arm g, with which it may engage when occasion requires. It is obvious that the tension that to the cords O, Oto properly 0 erate t e apparatus is limitedby the weight 0 the suspen ed parts, and in order tonse sprin s s'ufliciently strong to deliver the de--- slred low on the ring D the cord C is referably passed around the pulleys I an .J a

suflicient number of times to multiply" the force applied to the cord to the degree 'required to extend the springs. We have described the bell more particularly aso erated by the motion of the waves given to the boat; but it is evident that if the bell is hung by one cordfor example, C, thecord C can be alternately draw-n t ght and slackened by hand to operate the bell.

I We have shown the cord C as continuing down and around the pulleys I and J.

. substituted for the cord, either entire or for (See especially in Fig 3.) It is evident thata chain .or other flexible. connection may be so much of the cord as passes around these pulleys.'- Y

The details of the striking mechanism may be very greatly varied, an we donot limit our invention to the specific details of structure herein shown and described. The means,

ShQWI1,'l1OW8V8I", constitute the form in which we' refer to construct. the ap aratus, especial y for suspension from sma 1 boats to be olperated. either by the motion imparted to t e'boat by the waves or by hana 'orby any other mechanical expedient.
